ATENT ADJUSTABLE BINDING DEVICE FOR MILK-CANS.

SPECIFICATION forming part of Letters Patent No. 430,386, dated June 17, 1890.

Application filed June 21, 1889. Serial No. 315,113. (No model.)

and State of Massachusetts, have invented oertain new and useful Improvements in Cream- Separators, of which the following is a specification.

My invention is designed as an improvement on my patent, No. 337,266, of March 2, 1886, in which a separate cream-holder is adapted to be attached firmly and tightly to and detached from the open top of a milk-can. In the above-named patent, when the cream holder is tightly attached to the top of the milk-can and the valve in the bottom of the cream-holder is open, the rich new milk is poured through the top of the cream-holder, filling the milk-can and wholly or partly fill- Then when the cream has all been separated from the milk and risen in its holder the valve in the bottom of the latter is closed, and the cream-holder can then be detached from the milk-can, which contains the skim milk. A hook which is loosely hung on each end of a toggle-lever pivoted to the crealn-holderis adapted to hold the same tightly againstthe top of the milkcan by said hooks passing through eyes on the neck of the can. The above construction for holding the cream-holder to the can answers every purpose of making a water-tight joint between said holder and can until the interposed washer or washers get hard and old and lose their elasticity, or until thejournal-bearin gs or pivots ot' the toggle-lever have worn loose, (which they are apt to do by the pressure put upon them,) when, there being no adj ustability of the holding device, the can and holder being brought together no nearer than when the washers were new and elastic or than when the toggle-lever journals were firm, the joint between the can and cream- .holder will have grown less tight and apt to bind together, one above the other, any other similar vessels.

In the accompanying drawings, forming a part of this specification, Figure 1 illustrates a side elevation, partly broken off, of a milk-can and cream-holder upon the same, and with my improved holding and tightening device attached thereto; and Fig.2 is a front elevation of the same.

A is an ordinary milk-can, and B is its neck.

0 is the cream-holder, having the cylindrical base D,which fits into the neck Bot the can A.

F is a washer of some elastic material such as rubber-and which encircles the base D and interposes between the top edge of the can A and the shoulder G of the cream-holder.

H is a toggle-lever similar to that shown in my above-named patent, and pivoted at a a. Instead of the hooks of said patent, I use two arms I, one being pivoted to each end of the lever H. These arms I have lateral lugs b extending inward from near their lower ends.

Ext-ending vertically downward from the shoulder G of the cream-holder, and below the pivots a a, are two forked arms or projections J J, one beneath each pivot. When the arms I I are operated by the lever H, the lugs b b of each arm will rise or fall between the prongs c c of the projections J, and said forked projections will form vertical guides for said lugs. In order that the arms I I and their lugs b b may be prevented from swinging out from the can and cream-holder and held in to the same, a lug d extends laterally from and at right angles to each side of the lug b, and these two lugs d d bear against the inner surfaces of the prongs c c, the latter forming a stop to any outward swing of the arm I. The arms I curve slightly outward from their pivots e c to allow sufficient play for the togglelever H.

Extending laterally from the neck B of the cam, and on opposite sides of the same, are two inclined lugs or ears K K, each of which inclines in an opposite direction from the other, and extending downward from the lower extremity of each lug K is a small f- When the cream-holder O is placed upon the milk-can A, the arms I I should be just beyond the upper extremities g g of the ears K. Then by turning the holder 0 to the right the lugs b b will pass under the inclined ears K K, sliding down the same and tightening the holder 0 to the cam. Then by forcing down the toggle-lever H the lugs 19 b will be forced up upon the lower surfaces of the ears K K, binding the holder 0 to the can A and compressing the interposed washer, so as to form a water-tight joint. If the washer has lost its elasticity and become old, retaining its compressed and thin state, or if the togglelever journals have grown loose, the can and cream-holder can still be tightly pressed and held together, as the lugs b will ride farther down than formerly below the ears K, and then be drawn up tightly against the same. The lugs f f act as stops to the downward play of the lugs 19.

If desired, the position of the toggle-lever and its connecting parts and the inclined ears K K may be reversed, the former being attached to the milk-can and the latter to the cream-holder.

I claim 1. An adjustable device for holding and binding two vessels firmly together, one-upon the other, consisting in the two or more inclined lugs or ears K K, extending laterally from the outer surface of one of the vessels, and the incline of each ear being in a difierout direction from the other, in combination with two or more arms loosely attached to the other vessel near one end and having lugs at their free portions extending inward and for bearing against the lower inclined surface of the ears K K, and means for forcing the lugs of the arms up against said cars, all substantially as described.

2. An adjustable device for holding and binding two vessels firmly together, one upon the other, consisting in a toggle-lever pivoted to the side of one of the vessels, arms pivoted to the ends of said lever and having lateral lugs extending inward from the free portions of said arms, in combination with the inclined lugs or ears K K, extending laterally from extending laterally from the outer surface of one vessel, in combination with two or more arms loosely attached to the other vessel near one end and having lugs at their free portions extending inward and for bearing against the lower and inclined surface of said ears, and means for forcing the lugs of the arms up against said ears, all substantially as described.

4. An adjustable device for holding and binding two vessels firmly together, one upon the other, consisting in a toggle-lever pivoted to the side of one of the vessels, arms pivoted to the ends of said lever and having lateral lugs extending inward from the free portions of said arms, in combination with the forked guides J J and with the inclined lugs or ears extending laterally from the outer surface of the other vessel, all substantially as shown, and for the purposes described.

5. An adjustable device for holding and binding two vessels firmly together, one upon the other, consisting in a toggle-lever pivoted to the side of one of the vessels and having arms pivoted to the ends of said lever, and also having the lugs 17 and c c, in combination with the forked guides J J and with the inclined lugs or ears K K upon the outer surface of the other vessel, all substantially as shown, and for the purposes described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 19th day of June, A. D. 1889.

WILLIAM H. JOHNSON.
